BACKGROUND

Angiogenesis is a physiological process of growing new blood vessels from pre-existing vessels. It takes place in a healthy subject to heal wounds, i.e., restoring blood flow to tissues after injury or insult.

Excessive blood vessel growth may be triggered by certain pathological conditions such as cancer, age-related macular degeneration, rheumatoid arthritis, and psoriasis. As a result, new blood vessels feed diseased tissues and destroy normal tissues. In cancer, new blood vessels also allow tumor cells to escape into the circulation and lodge in other organs.

Vascular endothelial growth factor (VEGF), a homodimeric glycoprotein, and its receptors, e.g., kinase insert domain receptor (KDR), constitute an important angiogenic pathway. Studies have shown that inhibition of KDR resulted in endothelial cell apoptosis and, thus, suppression of angiogenesis. See Rubin M. Tuder, Chest, 2000; 117: 281. KDR inhibitors are therefore potential candidates for treating angiogenesis-related diseases.

Yet another aspect of this invention features a method of inhibiting angiogenesis, or treating age-related macular degeneration, by administrating to a subject in need thereof an effective amount of a pyrimidine compound of formula (II) as described above.

Also within the scope of this invention are (1) a composition containing one or more of the pyrimidine compounds described above and a pharmaceutically acceptable carrier for use in treating an angiogenesis-related disorder (e.g., such cancer or age-related macular degeneration) and (2) use of one or more of the pyrimidine compounds for the manufacture of a medicament for treating the disorder.

The details of one or more embodiments of the invention are set forth in the description below. Other features, objects and advantages of the invention will be apparent from the description and from the claims.

DETAILED DESCRIPTION

The compounds described above can be synthesized from commercially available starting materials by methods well known in the art. As an example, one can replace leaving groups (e.g., chloride, p-TsO, MeS, or MeSO₂) at the active N2, N4-positions of a suitable pyrimidine compound with nucleophilic groups such as amino or hydroxyl via, e.g., Buchwald-Hartwig coupling reaction. The replacement can be first effected either at the N2 position or the N4 position.

The compounds thus obtained can be further modified at their peripheral positions to provide the desired compounds.

Synthetic chemistry transformations useful in synthesizing desirable pyrimidine compounds are described, for example, in R. Larock, Comprehensive Organic Transformations, VCH Publishers (1989); T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 3^(rd) Ed., John Wiley and Sons (1999); L. Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, John Wiley and Sons (1994); and L. Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, John Wiley and Sons (1995) and subsequent editions thereof.

Before use, the compounds can be purified by column chromatography, high performance liquid chromatography, crystallization, or other suitable methods.

The pyrimidine compounds described above, when contacting with KDR, inhibit this receptor's activity. An effective amount of one or more of these compounds can be therefore used to inhibit angiogenesis and treat a subject having an angiogenesis-related disorder.

The term “an effective amount” refers to the amount of a pyrimidine compound that is required to confer the intended effect in the subject. Effective amounts may vary, as recognized by those skilled in the art, depending on route of administration, excipient usage, and the possibility of co-usage with other agents. The term “treating” refers to administering one or more of the above-described pyrimidine compounds to a subject that has an angiogenesis-related disorder, or has a symptom of the disorder, or has a predisposition toward the disorder, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve, or affect the disorder, the symptoms of the disorder, or the predisposition toward the disorder.

To practice this method, a composition having one or more of the pyrimidine compounds of this invention can be administered orally, parenterally, by inhalation spray, or via an implanted reservoir. The term “parenteral” as used herein includes subcutaneous, intracutaneous, intravenous, intramuscular, intraarticular, intraarterial, intrasynovial, intrasternal, intrathecal, intralesional and intracranial injection or infusion techniques.

An oral composition can be any orally acceptable dosage form including, but not limited to, tablets, capsules, emulsions and aqueous suspensions, dispersions and solutions. Commonly used carriers for tablets include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added to tablets. For oral administration in a capsule form, useful diluents include lactose and dried corn starch. When aqueous suspensions or emulsions are administered orally, the active ingredient can be suspended or dissolved in an oily phase combined with emulsifying or suspending agents. If desired, certain sweetening, flavoring, or coloring agents can be added.

A sterile injectable composition (e.g., aqueous or oleaginous suspension) can be formulated according to techniques known in the art using suitable dispersing or wetting agents (such as, for example, Tween 80) and suspending agents. The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are mannitol, water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium (e.g., synthetic mono- or di-glycerides). Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions can also contain a long-chain alcohol diluent or dispersant, or carboxymethyl cellulose or similar dispersing agents.

An inhalation composition can be prepared according to techniques well known in the art of pharmaceutical formulation and can be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other solubilizing or dispersing agents known in the art.

A topical composition can be formulated in form of oil, cream, lotion, ointment and the like. Suitable carriers for the composition include vegetable or mineral oils, white petrolatum (white soft paraffin), branched chain fats or oils, animal fats and high molecular weight alcohols (greater than C12). The preferred carriers are those in which the active ingredient is soluble. Emulsifiers, stabilizers, humectants and antioxidants may also be included as well as agents imparting color or fragrance, if desired. Additionally, transdermal penetration enhancers may be employed in these topical formulations. Examples of such enhancers can be found in U.S. Pat. Nos. 3,989,816 and 4,444,762. Creams are preferably formulated from a mixture of mineral oil, self-emulsifying beeswax and water in which mixture the active ingredient, dissolved in a small amount of an oil, such as almond oil, is admixed. An example of such a cream is one which includes about 40 parts water, about 20 parts beeswax, about 40 parts mineral oil and about 1 part almond oil. Ointments may be formulated by mixing a solution of the active ingredient in a vegetable oil, such as almond oil, with warm soft paraffin and allowing the mixture to cool. An example of such an ointment is one which includes about 30% by weight almond and about 70% by weight white soft paraffin.

A carrier in a pharmaceutical composition must be “acceptable” in the sense that it is compatible with active ingredients of the formulation (and preferably, capable of stabilizing it) and not deleterious to the subject to be treated. For example, solubilizing agents, such as cyclodextrins (which form specific, more soluble complexes with one or more of active pyrimidine compounds of the extract), can be utilized as pharmaceutical excipients for delivery of the active ingredients. Examples of other carriers include colloidal silicon dioxide, magnesium stearate, cellulose, sodium lauryl sulfate, and D&C Yellow #10.

Suitable in vitro assays can be used to preliminarily evaluate the efficacy of the above-described pyrimidine compounds in inhibiting the activity of KDR or inhibiting the activity of VEGF. The compounds can further be examined for its efficacy in treating an angiogenesis-related disorder by in vivo assays. For example, the compounds can be administered to an animal (e.g., a mouse model) having cancer and its therapeutic effects are then accessed. Based on the results, an appropriate dosage range and administration route can also be determined.

Without further elaboration, it is believed that the above description has adequately enabled the present invention. The following specific examples are, therefore, to be construed as merely illustrative, and not limitative of the remainder of the disclosure in any way whatsoever.

EXAMPLE 1 Synthesis of N4-(2-methyl-1H-indol-5-yl)-N2-phenylpyrimidine-2,4-diamine (Compound 1)

Et₃N (1 mmol) was added to a solution of 2,4-dichloropyrimidine (1 mmol) and 5-amino-2-methylindole (1 mmol) in 5 ml EtOH. The reaction mixture was refluxed for 5 hours. After removal of the solvent in vacuo and addition of H₂O, the mixture was extracted with EtOAc. The organic layers were combined, washed with saturated NaCl solution, dried over anhydrous Na₂SO₄, and concentrated in vacuo. The resulting residue was purified by column chromatography to give N-(2-chloropyrimidin-4-yl)-2-methyl-1H-indol-5-amine in a yield of 80%.

N-(2-chloropyrimidin-4-yl)-2-methyl-1H-indol-5-amine (0.1 mmol) and aniline (0.1 mmol) were dissolved in 0.5 ml DMF. To this was added p-TsOH monohydrate (0.2 mmol). The reaction mixture was stirred at 60° C. for 5 hours, diluted with water, and extracted with ethyl acetate. The organic layer was washed with water and brine sequentially, dried over anhydrous Na₂SO₄, and concentrated. The resulting residue was purified by column chromatography to provide the title product in a yield of 85%.

EXAMPLE 284 Synthesis of 3-(4-(2-methyl-1H-indol-5-ylamino)pyrimidin-2-ylamino)phenol (Compound 284)

A solution of N2-(3-methoxylphenyl)-N4-(2-methyl-1H-indol-5-yl)pyrimidine-2,4-diamine (0.1mmol) in 5 ml CH₂Cl₂ was placed in an ice bath. To this was added BBr₃(0.5 mmol). The reaction mixture was stirred overnight at room temperature, then poured into ice water, and extracted with ethyl acetate. The organic layer was washed sequentially with water and brine, dried over anhydrous Na₂SO₄, and concentrated. The residue was purified by column chromatography to provide the desired product in a yield of 83%.

EXAMPLE 318 KDR Kinase Activity Assay Using Z′-Lyte Kinase Assay Kit

Inhibition of kinase activity of a recombinant KDR catalytic domain (Invitrogen, Carlsbad, Calif., U.S.A., Cat. PV3660) was determined using Z′-LYTE™ Tyr1 Peptide assay kit (Invitrogen, Cat. PV3190) in a black 384-well plate (Thermo labsystems, Cambridge, U.K., Cat. 7805). The assay was performed according to the procedures recommended by the manufacturer.

Briefly, a test compound (10 mM stock in DMSO) was diluted to 1:4 with distilled water containing 8% DMSO. The solution was placed in a test well and three control wells (C1, C2, and C3) at 2.5 μl/well. Coumarin-fluorescein double-labeled peptide substrate was mixed with the KDR catalytic domain (“kinase”). 5 μl of the kinase/peptide mixture was added to each of the test, C1, and C2 wells, but not C3 (Final concentration: 0.3 μg/ml of Kinase, 2 μM of peptide). 5 μl of Phosphor-Tyr1 peptide was added to the C3 well. 2.5 μl of 40 μM ATP was added to the test well and C2 well and 2.5 μl of 1.33× kinase buffer (1× buffer: 50 mM HEPES, pH 7.5, 0.01% Brij-35, 5 mM MgCl₂, 5 mM MnCl₂, and 1 mM EGTA) was added to the C1 and C3 wells. The plate was briefly spun at 1000 rpm to settle all solution down to the bottom of the wells and then sealed and shaken at 250 rpm and 25° C. for 1 hour.

A development reagent was diluted to 1:128 according to the recommendation of the manufacturer. 5 μl of the diluted development reagent was added to each well. The plate was spun at 1000 rpm to settle all solution down to the wells, and then sealed and shaken at 250 rpm and 25° C. for 1 hour.

5 μl of a stop reagent was added to each well. The plate was spun at 1000 rpm to settle all solution down to the wells, and then sealed at 250 rpm and 25° C. for 2 minutes. Emission of the solution at each well was measured by a Victor™3 micro-plate reader at Excitation 400 nm/Emission 445 nm and 520 nm. The emission ratio and phosphorylation (“Phos.”) percentage were calculated by the following equations:

$\mspace{20mu}{{{Emission}\mspace{14mu}{Ratio}} = \frac{{Coumarin}\mspace{14mu}{Emission}\mspace{14mu}\left( {445\mspace{14mu}{nm}} \right)}{{Fluorescein}\mspace{14mu}{Emission}\mspace{14mu}\left( {520\mspace{14mu}{nm}} \right)}}$ ${\%\mspace{14mu}{Phosphorylation}} = {1 - \frac{\left( {{Emission}\mspace{14mu}{Ratio} \times F_{100\%}} \right) - C_{100\%}}{\left( {C_{0\%} - C_{100\%}} \right) + \left\lbrack {{Emission}\mspace{14mu}{Ratio} \times \left( {{F\; 100\%} - {F\; 0\%}} \right)} \right\rbrack}}$

-   -   where:     -   C_(100%)=Average Coumarin emission signal of the 100% Phos.         Control     -   C_(0%)=Average Coumarin emission signal of the 0% Phos. Control     -   F_(100%)=Average Fluorescein emission signal of the 100% Phos.         Control     -   F_(0%)=Average Fluorescein emission signal of the 0% Phos.         Control         The inhibition ratio was calculated as follows:         Inhibition %=(Phos. in C2 well−Phos. in test well)/(Phos. in C2         well)×100%

The result showed that all of the tested compounds inhibited the activity of KDR.

The IC₅₀ values ranged from 0.001 to 10 μM.
